The present invention relates to a process for the preparation of a catalyst system suitable for olefin polymerization wherein the external electron donor is n-propyltriethoxysilane, and a catalyst system obtained or obtainable by said process. The invention also relates to a process for preparing a polyolefin using said catalyst system. The invention further relates to a polyolefin, in particular polyprolyene, obtainable by such a process, and shaped articles manufactured from such a polymer. The polymers produced using the catalyst system exhibit low volatiles and therefore have a reduced environmental and health impact.
